Question

也许我在这里遗漏了一些简单的东西，但我不能为我的生活让URL使用他们的WhatsApp计划显示在URL应用上。我有：

        NSString *stringToSend = [[NSString stringWithFormat:@"whatsapp://send?text=myAppDomain://%@moreChars",specialString] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

        NSURL *whatsappURL = [NSURL URLWithString:stringToSend];

        [[UIApplication sharedApplication] openURL: whatsappURL];

它成功启动了WhatsApp应用，但是在我选择了一个联系人之后，消息框没有预先填充，它仍然是空的。我做错了什么？

最后，我得到了将自己的应用程序itunes URL分享给whatsapp的解决方案。

NSString *string = [@"" stringByAppendingFormat:@"Share this on whatsapp \n\n https://itunes.apple.com/us/app/google-search/id284815942?mt=8"];

 string = [string stringByReplacingOccurrencesOfString:@"=" withString:@"%3D"];
    string = [string stringByReplacingOccurrencesOfString:@"&" withString:@"%26"];

  NSLog(@">>>Just pass this to Whatspp using their URL scheme %@",string);

我测试得很好。 :) 祝你好运。

这是在WhatsApp

中发送文本和网址的完整代码

    NSString * msg = @"Application%20Name%20https://itunes.apple.com/YOUR-URL";

    msg = [msg stringByReplacingOccurrencesOfString:@":" withString:@"%3A"];
    msg = [msg stringByReplacingOccurrencesOfString:@"/" withString:@"%2F"];
    msg = [msg stringByReplacingOccurrencesOfString:@"?" withString:@"%3F"];
    msg = [msg stringByReplacingOccurrencesOfString:@"," withString:@"%2C"];
    msg = [msg stringByReplacingOccurrencesOfString:@"=" withString:@"%3D"];
    msg = [msg stringByReplacingOccurrencesOfString:@"&" withString:@"%26"];

    NSString * urlWhats = [NSString stringWithFormat:@"whatsapp://send?text=%@",msg];
    NSURL * whatsappURL = [NSURL URLWithString:urlWhats];
    if ([[UIApplication sharedApplication] canOpenURL: whatsappURL])
    {
        [[UIApplication sharedApplication] openURL: whatsappURL];
    }
    else
    {
        UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"WhatsApp not installed." message:@"Your device has no WhatsApp installed." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [alert show];
    }

Answer 3

你附加了字符串UTFEncoded吗？我的意思是这是你的解决方案。

Answer 4

使用WhatsApp stringByAddingPercentEscapesUsingEncoding是不够的。请尝试以下适用于我的代码：

NSString *theTempMessage,*theFinalMessage;
.......
    /// theTempMessage should contain your stringToSend (in its current state);
    theTempMessage = [theTempMessage stringByReplacingOccurrencesOfString:@":" withString:@"%3A"];
    theTempMessage = [theTempMessage stringByReplacingOccurrencesOfString:@"/" withString:@"%2F"];
    theTempMessage = [theTempMessage stringByReplacingOccurrencesOfString:@"?" withString:@"%3F"];
    theTempMessage = [theTempMessage stringByReplacingOccurrencesOfString:@"," withString:@"%2C"];
    theTempMessage = [theTempMessage stringByReplacingOccurrencesOfString:@"=" withString:@"%3D"];
    theFinalMessage = [theTempMessage stringByReplacingOccurrencesOfString:@"&" withString:@"%26"];
    stringToSend=theFinalMessage;

此时你的stringToSend应该包含一些有效的东西。请尝试一下，让我知道。

我希望这会有所帮助。
